An oceanographer sent me the following [edited]:
--- Assuming you are referring to the barotropic streamfunction. Computing this requires solving an elliptic equation, the details of which depend significantly on how one discretizes the differential operators that would be applied to u and v. If u and v are from a model, you would somehow need to inform the streamfunction solver of the model discretizations. I think it would be very challenging to write a general purpose tool for this task. (Our model computes this diagnostic online for the history files so that it doesn't have to be computed offline.) ---- >> >> On 3/3/11 7:42 AM, Elodie Burrillon wrote: >>> Hi, >>> >>> NCL-team, do you plan to build a function that computes the >>> streamfunction from u and v ? >>> >>> NCL-users, does anyone already built such a function or code? >>> >>> Thanks in advance, >>> >>> Elodie >>> _______________________________________________ >>> ncl-talk mailing list >>> List instructions, subscriber options, unsubscribe: >>> http://mailman.ucar.edu/mailman/listinfo/ncl-talk _______________________________________________ ncl-talk mailing list List instructions, subscriber options, unsubscribe: http://mailman.ucar.edu/mailman/listinfo/ncl-talkReceived on Thu Mar 3 09:00:14 2011
